I've never had a single problem with hosting multiple https domains using Nginx and Let's Encrypt. This article is somewhat baffling, considering his example of clients that need this is "mobile browsers" but I've used iOS and Android and it works just fine.
Me neither. I guess Cloudflare (to name but one service reliant on SNI) hasn't either...
This article is a bit of an unusual response to a problem of a device not working. When a device of mine doesn't work but others do I put it down to there being a problem with my device, not a widely used technology (like SNI).
